I used this with my Samsung Galaxy S5, with an otterbox on the phone. I was able to get the phone in with no problems. The only problem that I did have was, it was very difficult to keep it on my arm. I don't have big arms, but I couldn't get it tight enough so it wouldn't slide around and fall back down to my hand. Other than that, I was able to answer my phone, listen to music and play games on the phone without any problems.
